CVE-2021-28950

A denial of service in the kernel side of the FUSE functionality can allow a local system to create a denial of service.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

As the FUSE module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:

echo "install fuse /bin/true" >> /etc/modprobe.d/disable-fuse.conf

The system will need to be restarted if the FUSE modules are loaded. In most circumstances, the CIFS kernel modules will be unable to be unloaded while the FUSE filesystems are in use.

If the system requires this module to work correctly, this mitigation may not be suitable.
